Solution Summary
A shear stress problem for pitch circle diameters are determined.
Solution Preview
I find two essential and one secondary errors in your text:
(1) In your sentence "If PCD meant the diameter to start with this shear stress is 2 kN m / 200 mm ...". The error is that you divided the torque by the DIAMETER.
The correct formula ...
